OpenManage CMC Discovery Range

I'm fiddling with Open Manage Essentials Discovery Range right now because I discovered it wasn't inventorying all our FX2s chassis. I turned on CMC discovery for a certain range and now all CMCs are showing up as separate groups. The result is too cluttered and is not what I wanted. I want it to be clean like ECH-SRV grouping in my image but for some reason the HPC grouping is much messier despite setting them both up the same way. (Please refer to image) Each sub-group shows only one device as well.
